Interior
If ducting is not connected it is essential
that all inlets and discharge openings are completely sealed.

Exterior
The exterior shall be kept free from falling
building materials, dampness or extreme cold or heat. The unit exterior
surfaces should be inspected on a monthly basis and any sign of corrosion
or scratches are to be treated immediately.

Static Indentation
Machines fitted with ball bearings may be
damaged if left stationary for long periods. The balls and races may
suffer damage by fretting corrosion (false brinelling, stationary
vibration or static vibration marking).

Wedge Belts and Pulleys
Wedge belts should be removed from the pulleys
and hung up and not exposed to excessive heat or cold and kept free
from dampness. Belt life is reduced over a long period of non-use due
to the curing and static condition of rubber. Pulleys already taper-locked to shafts can be lightly covered with rustproof
compound. This must be thoroughly cleaned off before belting up prior
to start up.

Filters
All filters, whether in the form of bags or
panels, must be suitably wrapped and sealed to prevent damp and ingress
of dust or foreign bodies, and held in a dry store.

Fan Shaft Bearings
Refer to bearing damage in Cautionary Notes.
Bearings fitted with shields should not be stored for periods exceeding
two (2) years since the grease ages. Bearings stored for longer periods
than that specified may be found to have a higher initial starting
torque and the service life of the grease will then be shortened.
It is therefore advisable to repack the grease after twelve months
of non-use. Fan shafts and impellers should be protected with rustproof
compound to prevent any corrosion-taking place.

Electric Motors
Clean out all the dust accumulated inside and
outside the motor and make sure that all the component parts of the
motor are in good condition. Cover all the ventilating holes on the
motor frame to prevent dust from entering the motor. Apply a coating
of anti-corrosion grease or other anti-corrosion agent on all the parts
that may be subject to rusting. Care must be taken to see that the storeroom
is always dry and well ventilated while the room temperature is regularly
maintained above 0oC. During storage, periodic inspections should be
made to check for moisture, rust or hardening of grease.

The above are intended to preserve the life
of all static and moving parts of the equipment during the period
of storage. It is advisable that regular attention of the equipment
is maintained.
